Spline

The Spline tools generate controlled linear environment features such as fences, walls, paths, and repeated meshes. Use them when placement needs to follow a designed route rather than a broad biome or volume.

Use It When

• You need fences, walls, roads, paths, or repeated meshes along a route.
• You want designer-controlled placement without manually positioning every segment.
• You need generated content to follow a path through a biome, settlement, or gameplay space.

Integration Notes

• Keep spline shapes simple until the result is visually and mechanically stable.
• Check segment spacing, collision, and endpoint behavior after changing meshes.
• If the spline intersects PCG vegetation or props, use exclusions or filters so generated content does not fight the spline content.
• Validate navigation and player traversal when spline content becomes walls, fences, or blocking geometry.
